Introduction to Electrical Communication Systems

Catalog description

This course discusses topics such as transmission of signals, amplitude modulations and demodulations, frequency modulations and demodulations, phase modulations and demodulations, sampling and analog-to-digital conversion, and some applications of the sampling theorem such as Pulse Amplitude Modulation, Pulse Width Modulation and Pulse Code Modulation. Digital modulation schemes such Amplitude Shift Keying, Frequency Shift Keying, and Quadrature Amplitude are introduced. Bandwidth and signal to noise ratios are covered for each modulation scheme. Laboratory experiments and MATLAB experiments in analog and digital modulations and demodulations such as amplitude modulation and demodulation concepts, the relation between modulation index and bandwidth of FM, M-array communication systems, and Noise analysis in digital systems are conducted.
